Looking great. Maybe your first grow, but you clearly know what you're doing.
I love PC grows - there's just something really cool about seeing an innocent looking PC case sitting there and knowing it's full of live plants. I did PCs for years when I was working abroad. I spent time in a few crazy countries where they'd cut you knackers off for smoking a joint - and my job also meant big scandals if I ever got caught - so I learned a bit about this kind of grow.
It's always hard to prevent light leaks on a real stealth PC grow, but I'm assuming your in no danger there.
Anyways.... all the best. Will pop in regularly to see how it's going. Have fun...
